CoQ10 is a naturally occurring enzyme that exists in the human body. It is involved in the production of energy in the body. The chief source of energy in the human body is adenosine triphosphate also referred to as ‘ATP’. CoQ10 is involved in the breakdown of ATP. This process occurs in all the muscles of the human body including the heart muscles. Thus CoQ10 supplements can be used to increase the efficiency of the heart which is severely affected in many cardiovascular diseases.


How CoQ10 Can Help To Improve Cardiac Functions

CoQ10 performs the following major functions:

  • It is involved in the release of energy from ATP.
  • It is involved in the mobilization of fats from the adipose tissues.
  • It helps to lower the LDL levels in blood.
  • It acts as an antioxidant.

These functions affect the cardiovascular system in the following ways:
The damage to the myocardium can occur due to many different factors. As a result of this damage there is an imbalance between myocardial energy demands and supplies. CoQ10 can replenish these energy demands due to their involvement in energy production from ATP as thus can be helpful in cardiovascular diseases.

CoQ10 is involved in improving the elasticity of the arteries. This function has a significant effect in the case of hypertension. As in hypertension there is an increase pressure of blood on the walls of the arteries. As the elasticity of the arteries is increased they become able to cope with this increased pressure and as a result the risk of hypertension is decreased. In atherosclerosis the elasticity of the arteries is lost. This increases the chances of damage to the arterial endothelium which can have drastic effects as this can cause thrombosis and myocardial infarction. So the increased elasticity due to CoQ10 decreases the chances of myocardial infarction.

CoQ10 is a potent antioxidant. There are some chemical species in our body produced as a result of different chemical reactions in the body. These chemical species are called ‘free radicals’. These free radicals can cause damage to the vascular endothelium. The damaged endothelium can become a site of fatty plaque formation also called as atherosclerosis which is a major cause of many cardiovascular problems. The antioxidant effect of CoQ10 helps in the removal and neutralization of these free radicals and as a result the chances of endothelial damage are minimized.

The lipid lowering effect of CoQ10 is also helpful in the prevention of heart problems. CoQ10 is involved in the oxidation and mobilization of LDL which is the type of lipids responsible for all the heart related problems. As the levels of LDL decrease so does the risk of cardiovascular disease.

The overall effect of CoQ10 on cardiovascular function is that it increases the flow of blood to the heart, has a positive effect on the blood pressure and also keeps the levels of LDL in blood within a normal healthy range. Thus it has an overall healthy effect on the functioning of cardiovascular system. Thus it is suggested by many researchers that CoQ10 should be used for the treatment and improvements of cardiovascular problems. The usual recommended CoQ10 dosage in order to have significant effects is 300 mg/day for 12 weeks. But this dosing schedule varies in different conditions.
